Digital imaging systems and methods of analyzing pixel data of an image of a user&#39;s body for determining a hair growth direction value of the user&#39;s hair

ABSTRACT

Artificial intelligence based systems and methods are described for analyzing pixel data of an image of a user&#39;s body for determining a hair growth direction value of the user&#39;s hair. An example method includes aggregating a plurality of training images of a plurality of users&#39; bodies, and training a hair growth direction model operable to output a hair growth direction value. The example method may further include receiving an image of a user comprising pixel data of a portion of the user&#39;s body or body area, and analyzing, by the hair growth direction model, the image to determine a user-specific hair growth direction value of the user&#39;s hair. The example method may further include generating a product recommendation, wherein the product is designed to address a feature identifiable within the pixel data of the user&#39;s body or body area.

FIELD

The present disclosure generally relates to digital imaging systems and methods, and more particularly to, digital imaging systems and methods for analyzing pixel data of an image of a user's body for determining a hair growth direction value of the user's hair.

BACKGROUND

Generally, shave performance can be summarized as a trade-off between closeness and irritation, where a user typically can either achieve, on the one hand, a closeness of shave (removing more hair) but at the risk of irritation, redness, or cuts of his or her skin, or, on the other hand, a less close shave (leaving more hair) but reducing the risk of skin irritation. The closeness of shave can in large part depend on the direction an individual chooses to move the razor relative to the direction of their hair growth. In particular, if an individual shaves in the opposite direction of their hair growth (i.e., “against the grain”), the individual will likely experience a closer shave than if the individual shaves in the same direction of their hair growth (i.e., “with the grain”). In an attempt to achieve a similar close-shave feel, individuals shaving with the grain may apply more pressure with the razor or perform multiple shaving strokes, thereby increasing their chances for skin irritation or cuts. On the other hand, shaving against the grain can more easily irritate skin, damage hair follicles, and result in ingrown hairs than shaving with the grain. Many individuals may either be unaware of one or both shaving techniques, or may be unaware of their hair growth direction. In either case, these individuals risk engaging in an unsatisfactory shaving experience and perpetuating the trade-off between closeness and irritation.

Thus a problem arises for existing shaving razors, and the use thereof, where users with an unknown hair growth direction desiring a close, complete shave generally perform too many shaving strokes, apply too much pressure during a shave session, or cut their skin by unknowingly shaving against the grain. The problem is acutely pronounced given the myriad of directions a particular user's hair may grow in any location on their body. A user cannot rely on the direction of hair growth in one area of their body (or sometimes even on location on a single body part) to account for the hair growth direction on other body parts. Moreover, skin sensitivity can vary across different areas of the body, such that a user may be comfortable shaving against the grain at one location and not at another.

To further compound these problems, user's often struggle when deciding on which hair style to adopt. This confusion or hesitation can stem from a lack of understanding related to their hair growth direction in numerous areas of their body, which impacts the overall appearance/effectiveness of many popular hair styles. As a result, many users purchase incorrect or unnecessary products for their desired hair style, and/or otherwise have unpleasant shaving/trimming experiences because they fail to purchase products that would lessen skin irritation and the risk of skin cuts. This problem is particularly acute because such existing shaving razors and accompanying products provide little or no feedback or guidance to assist the user in achieving certain hair styles or making prudent grooming choices without skin irritation based on their specific hair growth direction.

For the foregoing reasons, there is a need for digital imaging systems and methods for analyzing pixel data of an image of a user's body for determining a hair growth direction value of the user's hair.

SUMMARY

Generally, as described herein, the digital systems and methods for analyzing pixel data of an image of a user's body for determining a hair growth direction value of the user's hair provide a digital imaging, and artificial intelligence (AI), based solution for overcoming problems that arise when determining adequate shaving products and/or technique based on a user's hair growth direction. The digital systems and methods allow a user to submit a specific user image to imaging server(s) (e.g., including its one or more processors), or otherwise a computing device (e.g., such as locally on the user's mobile device), where the imaging server(s) or user computing device implements or executes a hair growth direction model trained with pixel data of potentially 10,000s (or more) images of users with varying hair growth direction values. The hair growth direction model may generate, based on a determined user-specific hair growth direction value, at least one product recommendation for a manufactured product designed to address at least one feature identifiable within the pixel data of the user's body or body area. For example, the at least one feature can comprise pixels or pixel data indicative of an upward hair growth direction value in a concentrated region of the user's skin. In some embodiments, the at least one product recommendation may be rendered, on a display screen of a user computing device. In other embodiments, no transmission to the imaging server of the user's specific image occurs, where the product recommendation may instead be generated by the hair growth direction model, executing and/or implemented locally on the user's mobile device and rendered, by a processor of the mobile device, on a display screen of the mobile device. In various embodiments, such rendering may include graphical representations, overlays, annotations, and the like for addressing the feature in the pixel data.

More specifically, as describe herein, a digital imaging method of analyzing pixel data of an image of a user's body for determining a hair growth direction value of the user's hair is disclosed. The digital imaging method comprises aggregating, at one or more processors communicatively coupled to one or more memories, a plurality of training images of a plurality of users, each of the training images comprising pixel data of a respective user's body or body area. The digital imaging method further includes training, by the one or more processors with the pixel data of the plurality of training images, a hair growth direction model comprising a hair growth direction map and operable to output, across a range of the hair growth direction map, hair growth direction values associated with a hair growth direction ranging from upward to downward. The digital imaging method further includes receiving, at the one or more processors, at least one image of a user, the at least one image captured by a digital camera, and the at least one image comprising pixel data of the user's body or body area. The digital imaging method further includes analyzing, by the hair growth direction model executing on the one or more processors, the at least one image captured by the digital camera to determine a user-specific hair growth direction value of the user's hair. The digital imaging method further includes generating, by the one or more processors based on the user-specific hair growth direction value, at least one product recommendation for a manufactured product, the manufactured product designed to address at least one feature identifiable within the pixel data of the user's body or body area.

In addition, as described herein, a digital imaging system is configured to analyze pixel data of an image of a user's body for determining a hair growth direction value of the user's hair is disclosed. The digital imaging system comprises an imaging server comprising a server processor and a server memory; an imaging application (app) configured to execute on a user computing device comprising a device processor and a device memory, and the imaging app communicatively coupled to the imaging server; and a hair growth direction model comprising a hair growth direction map, trained with pixel data of a plurality of training images of a plurality of users and operable to output, across a range of the hair growth direction map, hair growth direction values associated with a hair growth direction ranging from upward to downward. The hair growth direction model is configured to execute on the server processor or the device processor to cause the server processor or the device processor to: receive at least one image of a user, the at least one image captured by a digital camera, and the at least one image comprising pixel data of the user's body or body area; analyze, by the hair growth direction model, the at least one image captured by the digital camera to determine a user-specific hair growth direction value of the user's hair; generate, based on the user-specific hair growth direction value, at least one product recommendation for a manufactured product, the manufactured product designed to address at least one feature identifiable within the pixel data of the user's body or body area; and render, on a display screen of the user computing device of the user, the at least one product recommendation.

Further, as described herein, a tangible, non-transitory computer-readable medium storing instructions for analyzing pixel data of an image of a user's body for determining a hair growth direction value of the user's hair is disclosed. The instructions, when executed by one or more processors cause the one or more processors to: aggregate, at one or more processors communicatively coupled to one or more memories, a plurality of training images of a plurality of users, each of the training images comprising pixel data of a respective user's body or body area; train, by the one or more processors with the pixel data of the plurality of training images, a hair growth direction model comprising a hair growth direction map and operable to output, across a range of the hair growth direction map, hair growth direction values associated with a hair growth direction ranging from upward to downward; receive, at the one or more processors, at least one image of a user, the at least one image captured by a digital camera, and the at least one image comprising pixel data of the user's body or body area; analyze, by the hair growth direction model executing on the one or more processors, the at least one image captured by the digital camera to determine a user-specific hair growth direction value of the user's hair; generate, by the one or more processors based on the user-specific hair growth direction value, at least one product recommendation for a manufactured product, the manufactured product designed to address at least one feature identifiable within the pixel data of the user's body or body area; and render, on a display screen of a user computing device, the product recommendation.

In accordance with the above, and with the disclosure herein, the present disclosure includes improvements in computer functionality or in improvements to other technologies at least because the disclosure describes that, e.g., an imaging server, or otherwise computing device (e.g., a user computing device), is improved where the intelligence or predictive ability of the imaging server or computing device is enhanced by a trained (e.g., machine learning trained) hair growth direction model. The hair growth direction model, executing on the imaging server or user computing device, is able to accurately identify, based on pixel data of other users, a user-specific hair growth direction value and at least one product recommendation for a manufactured product designed to address at least one feature identifiable within the pixel data of the user's body or body area. That is, the present disclosure describes improvements in the functioning of the computer itself or “any other technology or technical field” because an imaging server or user computing device, is enhanced with a plurality of training images (e.g., 10,000s of training images and related pixel data) to accurately predict, detect, or determine pixel data of a user-specific image(s), such as newly provided customer images. This improves over the prior art at least because existing systems lack such predictive or classification functionality and are simply not capable of accurately analyzing user-specific images to output a predictive result to address at least one feature identifiable within the pixel data of the user's body or body area.

For similar reasons, the present disclosure relates to improvement to other technologies or technical fields at least because the present disclosure describes or introduces improvements to computing devices in the field of shaving razors and accompanying products, whereby the trained hair growth direction model executing on the imaging devices or computing devices improve the field of shaving and/or shaving devices with digital and/or artificial intelligence based analysis of user-specific images to output a predictive result to address user-specific pixel data of at least one feature identifiable within the pixel data of the user's body or body area.

In addition, the present disclosure includes specific features other than what is well-understood, routine, conventional activity in the field, or adding unconventional steps that confine the claim to a particular useful application, e.g., analyzing pixel data of an image of a user's body for determining a hair growth direction value of the user's hair as described herein.

Additionally or alternatively, a user computer device may comprise, implement, have access to, render, or otherwise expose, at least in part, an interface or a guided user interface (GUI) for displaying text and/or images on its display screen.

FIGS. 2A-2C illustrate example images 202 a, 202 b, and 202 c that may be collected or aggregated at imaging server(s) 102 and may be analyzed by, and/or used to train, a hair growth direction model (e.g., an AI model such as a machine learning imaging model as describe herein). Each of these images may comprise pixel data (e.g., RGB data) corresponding representing feature data and corresponding to each of the personal attributes of the respective users 202 au, 202 bu, and 202 cu, within the respective image. The pixel data may be captured by a digital camera of one of the user computing devices (e.g., one or more user computer devices 111 c 1-111 c 3 and/or 112 c 1-112 c 3). In various embodiments, the at least one image of the user may be captured by the digital camera in conjunction with a hair removal event associated with at least a portion of the user's body or body area represented in the at least one image of the user. For example, the at least one image may be captured within 24 hours of when a user intends and/or has recently shaved/trimmed their body or body area.

Generally, as described herein, pixel data (e.g., pixel data 202 ap, 202 bp, and/or 202 cp) comprises user points or squares of data within an image, where each point or square represents a single pixel (e.g., pixel 202 ap 1 and pixel 202 ap 2) within an image. Each pixel may be a specific location within an image. In addition, each pixel may have a specific color (or lack thereof). Pixel color may be determined by a color format and related channel data associated with a given pixel. For example, a popular color format includes the red-green-blue (RGB) format having red, green, and blue channels. That is, in the RGB format, data of a pixel is represented by three numerical RGB components (Red, Green, Blue), that may be referred to as a channel data, to manipulate the color of pixel's area within the image. In some implementations, the three RGB components may be represented as three 8-bit numbers for each pixel. Three 8-bit bytes (one byte for each of RGB) is used to generate 24 bit color. Each 8-bit RGB component can have 256 possible values, ranging from 0 to 255 (i.e., in the base 2 binary system, an 8 bit byte can contain one of 256 numeric values ranging from 0 to 255). This channel data (R, G, and B) can be assigned a value from 0 255 and be used to set the pixel's color. For example, three values like (250, 165, 0), meaning (Red=250, Green=165, Blue=0), can denote one Orange pixel. As a further example, (Red=255, Green=255, Blue=0) means Red and Green, each fully saturated (255 is as bright as 8 bits can be), with no Blue (zero), with the resulting color being Yellow. As a still further example, the color black has an RGB value of (Red=0, Green=0, Blue=0) and white has an RGB value of (Red=255, Green=255, Blue=255). Gray has the property of having equal or similar RGB values. So (Red=220, Green=220, Blue=220) is a light gray (near white), and (Red=40, Green=40, Blue=40) is a dark gray (near black).

In this way, the composite of three RGB values creates the final color for a given pixel. With a 24-bit RGB color image using 3 bytes there can be 256 shades of red, and 256 shades of green, and 256 shades of blue. This provides 256×256×256, i.e., 16.7 million possible combinations or colors for 24 bit RGB color images. In this way, the pixel's RGB data value shows how much of each of Red, and Green, and Blue the pixel is comprised of. The three colors and intensity levels are combined at that image pixel, i.e., at that pixel location on a display screen, to illuminate a display screen at that location with that color. It is to be understood, however, that other bit sizes, having fewer or more bits, e.g., 10-bits, may be used to result in fewer or more overall colors and ranges.

As a whole, the various pixels, positioned together in a grid pattern, form a digital image (e.g., pixel data 202 ap, 202 bp, and/or 202 cp). A single digital image can comprise thousands or millions of pixels. Images can be captured, generated, stored, and/or transmitted in a number of formats, such as JPEG, TIFF, PNG and GIF. These formats use pixels to store represent the image.

FIG. 2A illustrates an example image 202 a and its related pixel data (e.g., pixel data 202 ap) that may be used for training and/or implementing a hair growth direction model (e.g., hair growth direction model 108), in accordance with various embodiments disclosed herein. Example image 202 a illustrates a user 202 au or individual displaying hair growth at a body area location comprising the user's neck. For example, image 202 a may represent the user 202 au displaying their hair growth on their neck before they attempt to shave their neck. Alternatively, image 202 a may represent the user 202 au displaying their hair growth on their neck after they have trimmed their neck and/or while the user 202 au is in the process of shaving/trimming their neck. In various embodiments, the user's body area location may comprise at least one of user's face, the user's cheek, the user's neck, the user's jaw, the user's head, the user's groin, the user's underarm, the user's chest, the user's back, the user's leg, the user's arm, or the user's bikini area.

Image 202 a is comprised of pixel data, including pixel data 202 ap. Pixel data 202 ap includes a plurality of pixels including pixel 202 ap 1 and pixel 202 ap 2. Pixel 202 ap 1 is a dark pixel (e.g., a pixel with low R, G, and B values) positioned in image 202 a resulting from user 202 au having a relatively high degree of hair growth at the position represented by pixel 202 ap 1 due to, for example, the hair on the user's 202 au neck approaching a dense region of user's 202 au facial hair (e.g., on the user's 202 au jaw). Pixel 202 ap 2 may be a similarly dark pixel positioned in image 202 a resulting from user 202 au having a similarly high degree of hair growth direction at the position represented by pixel 202 ap 2. However, the hair growth direction value of the hair represented by pixel 202 ap 1 may be different than the hair growth direction value of the hair represented by pixel 202 ap 2. For example the hair growth direction value of the hair represented by pixel 202 ap 1 may be to the left of the center of the user's neck from the user's perspective, while the hair growth direction value of the hair represented by pixel 202 ap 2 may be to the right of the center of the user's neck from the user's perspective.

Pixel data 202 ap includes various remaining pixels including remaining portions of the user's neck area featuring varying hair growth direction values (e.g., more upward near the center of the user's neck, more downward near the edges of the user's neck, etc.). Pixel data 202 ap further includes pixels representing further features including the undulations of the user's skin due to anatomical features of the neck and other features as shown in FIG. 2A.

FIG. 2B illustrates a further example image 202 b and its related pixel data (e.g., pixel data 202 bp) that may be used for training and/or implementing a hair growth direction model (e.g., hair growth direction model 108), in accordance with various embodiments disclosed herein. Example image 202 b illustrates a user 202 bu displaying hair growth at a body area location comprising the user's jaw. For example, image 202 b may represent the user 202 bu displaying their hair growth on their jaw before they attempt to shave their jaw. Alternatively, image 202 b may represent the user 202 bu displaying their hair growth on their jaw after they have trimmed their jaw and/or while the user 202 bu is in the process of shaving/trimming their jaw.

Image 202 b is comprised of pixel data, including pixel data 202 bp. Pixel data 202 bp includes a plurality of pixels including pixel 202 bp 1 and pixel 202 bp 2. Pixel 202 bp 1 may be a light pixel (e.g., a pixel with high R, G, and/or B values) positioned in image 202 b resulting from user 202 bu having a relatively low degree of hair growth at the position represented by pixel 202 bp 1. Pixel 202 bp 1 is a dark pixel (e.g., a pixel with low R, G, and B values) positioned in image 202 b resulting from user 202 bu having a relatively high degree of hair growth at the position represented by pixel 202 bp 2 due to, for example, the hair on the user's 202 bu jaw representing a denser region of user's 202 bu facial hair than the region represented by pixel 202 bp 1. The hair growth direction value of the hair represented by pixel 202 bp 1 may be different than the hair growth direction value of the hair represented by pixel 202 bp 2. For example the hair growth direction value of the hair represented by pixel 202 bp 1 may be slightly to the right of the center of the user's jaw from the user's perspective, while the hair growth direction value of the hair represented by pixel 202 bp 2 may be downward and in-line with the center of the user's jaw from the user's perspective.

Pixel data 202 bp includes various remaining pixels including remaining portions of the user's jaw area featuring varying hair growth direction values (e.g., more downward oriented hair growth near the user's jawline, slightly right/left growing hair nearer to the user's cheek, etc.). Pixel data 202 bp further includes pixels representing further features including the undulations of the user's skin due to anatomical features of the jaw and other features as shown in FIG. 2B.

FIG. 2C illustrates a further example image 202 c and its related pixel data (e.g., 202 cp) that may be used for training and/or implementing a hair growth direction model (e.g., hair growth direction model 108), in accordance with various embodiments disclosed herein. Example image 202 c illustrates a user 202 cu displaying hair growth at a body area location comprising the user's cheek. For example, image 202 c may represent the user 202 cu displaying their hair growth on their cheek before they attempt to shave their cheek. Alternatively, image 202 c may represent the user 202 cu displaying their hair growth on their cheek after they have cleanly shaven their cheek and/or while the user 202 bu is in the process of shaving/trimming their cheek.

Image 202 c is comprised of pixel data, including pixel data 202 cp. Pixel data 202 cp includes a plurality of pixels including pixel 202 cp 1 and pixel 202 cp 2. Pixel 202 cp 1 is a dark pixel (e.g., a pixel with low R, G, and B values) positioned in image 202 c resulting from user 202 cu having a relatively high degree of hair growth at the position represented by pixel 202 cp 1. Pixel 202 cp 2 is a light pixel (e.g., a pixel with high R, G, and/or B values) positioned in image 202 c resulting from user 202 cu having a relatively low degree of hair growth at the position represented by pixel 202 cp 2 due to, for example, no hair growth on the user's 202 cu cheek at the position represented by pixel 202 cp 2. The hair growth direction value of the hair represented by pixel 202 cp 1 may be different than the hair growth direction value of the hair represented by pixel 202 cp 2. For example the hair growth direction value of the hair represented by pixel 202 cp 1 may be slightly to the left of the center of the user's face from the user's perspective.

By contrast, the hair growth direction model may be unable to determine a hair growth direction value for the hair represented by pixel 202 bp 2 because it is too short for the model to make an accurate determination. However, the model may recognize the portion of the user's face represented by pixel 202 cp 2, based on prior images of the user, and make a determination based upon the prior images. For example, if the user previously submitted an image containing pixel data representative of the location on the user's face represented by pixel 202 cp 2, the model may determine the hair growth direction value for the hair represented by pixel 202 cp 2 to be the same as the previously determined hair growth direction value from the previously submitted image. Thus, if the previously determined hair growth direction value is far to the left of the center of the user's face from the user's perspective, then the hair growth direction model may determine the hair growth direction value for the hair represented by pixel 202 cp 2 to be far to the left of the center of the user's face from the user's perspective.

Pixel data 202 cp includes various remaining pixels including remaining portions of the user's cheek area featuring varying hair growth direction values (e.g., more downward further from the user's cheek, further to the right nearer to the user's cheek, etc.). Pixel data 202 cp further includes pixels representing further features including the undulations of the user's skin due to anatomical features of the cheek and other features as shown in FIG. 2C.

It is to be understood that each of the images represented in FIGS. 2A-2C may represent a user or user (e.g., users 202 au-202 cu) at any point before, during, and/or after a shave and/or trim. For example, image 202 a may represent the user 202 au before they attempt to shave/trim their neck area, image 202 b may represent the user 202 bu during a shave/trim of their jaw area, and image 202 c may represent the user 202 cu after they have shaved/trimmed their cheek area. Moreover, such images may arrive and be processed in accordance with a hair growth direction model (e.g., hair growth direction model 108), as described further herein, in real-time and/or near real-time. For example, the user 202 bu may capture image 202 b during a shave/trim, and the hair growth direction model may provide feedback, recommendations, and/or other comments in real-time or near real-time.

FIG. 3 illustrates a diagram of a digital imaging method 300 of analyzing pixel data of an image (e.g., images 202 a, 202 b, and/or 202 c) of a user's body for determining a hair growth direction value of the user's hair, in accordance with various embodiments disclosed herein. Images, as described herein, are generally pixel images as captured by a digital camera (e.g., a digital camera of user computing device 111 c 1). In some embodiments an image may comprise or refer to a plurality of images such as a plurality of images (e.g., frames) as collected using a digital video camera. Frames comprise consecutive images defining motion, and can comprise a movie, a video, or the like.

At block 302, method 300 comprises aggregating, at one or more processors communicatively coupled to one or more memories, a plurality of training images of a plurality of users, each of the training images comprising pixel data of a respective user's body or body area. For example, the pixel data may represent a respective user's neck (e.g., as illustrated in FIG. 2A), a respective user's jaw (e.g., as illustrated in FIG. 2B), a respective user's cheek (e.g., as illustrated in FIG. 2C), a respective user's head, a respective user's groin, a respective user's underarm, a respective user's chest, a respective user's back, a respective user's leg, a respective user's arm, and/or a respective user's bikini area.

At block 304 method 300 comprises training, by the one or more processors with the pixel data of the plurality of training images, a hair growth direction model (e.g., hair growth direction model 108) comprising a hair growth direction map and operable to output, across a range of the hair growth direction map, hair growth direction values associated with a hair growth direction ranging from upward to downward. The hair growth direction map can be an internalized map or otherwise custom map, unique to the hair growth direction model, where a upward hair growth direction value may be determined from an image or set of images having skin areas with upward hair growth direction values, i.e., images where the pixel data indicates that a skin area includes a high number of hair follicles growing in an upward direction relative to the user's perspective. Similarly, a downward hair growth direction value may be determined from an image or set of images having skin areas with downward hair growth direction values, i.e., images where the pixel data indicates that a skin area includes a high number of hair follicles growing in a downward direction relative to the user's perspective. Moreover, hair growth direction values may be determined at the pixel level or for a given skin area (e.g., one or more pixels) in an image.

In some embodiments, the hair growth direction map include a graphical overlay over a user submitted image (e.g., images 202 a-202 c) detailing the various hair growth direction values of hair follicles within a region of interest (e.g., pixel data 202 a-202 c). For example, the hair growth direction map graphically display hair growth direction values in the region of interest by placing arrows indicating the hair growth direction value over the corresponding portion of the region of interest (e.g., a right-facing arrow over the region including pixel 202 ap 2, a left-facing arrow over the region including pixel 202 ap 1, etc.). Other graphical overlays may include, for example, a heat mapping, where a specific color scheme overlaid onto the hair growth direction map indicates a magnitude or a direction of hair growth. The hair growth direction map may also include textual overlays configured to annotate the directions and/or their relative magnitudes indicated by the arrow(s) and/or other graphical overlay. For example, the hair growth direction map may include text such as “Right,” “Upward,” “Downward,” “Left,” etc. to describe the direction indicated by the arrow and/or other graphical representation.

Additionally or alternatively, the hair growth direction map may include a percentage scale or other numerical indicator to supplement the arrows and/or other graphical indicator. For example, the hair growth direction map may include hair growth direction values from 0% to 100%, where 0% represents least hair growth direction in a particular direction and 100% represents most hair growth direction in a particular direction. Values can range across this map where a hair growth direction value of 67% represents one or more pixels of a skin area detected within an image that has a higher hair growth direction value in a particular direction than a hair growth direction value of 10% in that particular direction as detected for one or more pixels of a skin area within the same image or a different image (of the same or different user). Moreover, the percentage scale or other numerical indicators may be used internally when the hair growth direction model outputs the hair growth direction values as part of the determination of a size and/or direction of the arrows and/or other graphical indicators.

In some embodiments, the hair growth direction map may be a numerical or decimal based scale, e.g., outputting hair growth direction values, e.g., from 0 to 10, where 0 represents least hair growth direction in a particular direction and 10 represents most hair growth in a particular direction. Values can range across this map where a hair growth direction value of 78.9 represents one or more pixels of a skin area detected within an image that has a higher hair growth direction value in a particular direction than a hair growth direction value of 21.3 in the particular direction as detected for one or more pixels of a skin area within the same image or a different image (of the same or different user).

In some embodiments, a comprehensive hair growth direction value, which can be a user-specific hair growth direction value as described herein, may be determined by averaging (or otherwise statistically analyzing) hair growth direction values for one or more pixels of a given skin area.

In various embodiments, hair growth direction model is an artificial intelligence (AI) based model trained with at least one AI algorithm. Training of hair growth direction model 108 involves image analysis of the training images to configure weights of hair growth direction model 108, and its underlying algorithm (e.g., machine learning or artificial intelligence algorithm) used to predict and/or classify future images. For example, in various embodiments herein, generation of hair growth direction model 108 involves training hair growth direction model 108 with the plurality of training images of a plurality of users, where each of the training images comprise pixel data of a respective user's body or body area. In some embodiments, one or more processors of a server or a cloud-based computing platform (e.g., imaging server(s) 102) may receive the plurality of training images of the plurality of users via a computer network (e.g., computer network 120). In such embodiments, the server and/or the cloud-based computing platform may train the hair growth direction model with the pixel data of the plurality of training images.

In various embodiments, a machine learning imaging model, as described herein (e.g., hair growth direction model 108), may be trained using a supervised or unsupervised machine learning program or algorithm. The machine learning program or algorithm may employ a neural network, which may be a convolutional neural network, a deep learning neural network, or a combined learning module or program that learns in two or more features or feature datasets (e.g., pixel data) in a particular areas of interest. The machine learning programs or algorithms may also include natural language processing, semantic analysis, automatic reasoning, regression analysis, support vector machine (SVM) analysis, decision tree analysis, random forest analysis, K-Nearest neighbor analysis, naïve Bayes analysis, clustering, reinforcement learning, and/or other machine learning algorithms and/or techniques. In some embodiments, the artificial intelligence and/or machine learning based algorithms may be included as a library or package executed on imaging server(s) 102. For example, libraries may include the TENSORFLOW based library, the PYTORCH library, and/or the SCIKIT-LEARN Python library.

Machine learning may involve identifying and recognizing patterns in existing data (such as training a model based on pixel data within images having pixel data of a respective user's body or body area) in order to facilitate making predictions or identification for subsequent data (such as using the model on new pixel data of a new user in order to determine a hair growth direction value of the specific user's hair).

Machine learning model(s), such as the hair growth direction model described herein for some embodiments, may be created and trained based upon example data (e.g., “training data” and related pixel data) inputs or data (which may be termed “features” and “labels”) in order to make valid and reliable predictions for new inputs, such as testing level or production level data or inputs. In supervised machine learning, a machine learning program operating on a server, computing device, or otherwise processor(s), may be provided with example inputs (e.g., “features”) and their associated, or observed, outputs (e.g., “labels”) in order for the machine learning program or algorithm to determine or discover rules, relationships, patterns, or otherwise machine learning “models” that map such inputs (e.g., “features”) to the outputs (e.g., labels), for example, by determining and/or assigning weights or other metrics to the model across its various feature categories. Such rules, relationships, or otherwise models may then be provided subsequent inputs in order for the model, executing on the server, computing device, or otherwise processor(s), to predict, based on the discovered rules, relationships, or model, an expected output.

In unsupervised machine learning, the server, computing device, or otherwise processor(s), may be required to find its own structure in unlabeled example inputs, where, for example multiple training iterations are executed by the server, computing device, or otherwise processor(s) to train multiple generations of models until a satisfactory model, e.g., a model that provides sufficient prediction accuracy when given test level or production level data or inputs, is generated. The disclosures herein may use one or both of such supervised or unsupervised machine learning techniques.

Image analysis may include training a machine learning based model (e.g., the hair growth direction model) on pixel data of images of one or more user's body or body area. Additionally, or alternatively, image analysis may include using a machine learning imaging model, as previously trained, to determine, based on the pixel data (e.g., including their RGB values) of the one or more images of the user(s), a hair growth direction value of the specific user's hair. The weights of the model may be trained via analysis of various RGB values of user pixels of a given image. For example, dark or low RGB values (e.g., a pixel with values R=25, G=28, B=31) may indicate a high hair growth area of the user's skin. A red toned RGB value (e.g., a pixel with values R=215, G=90, B=85) may indicate irritated skin. A lighter RGB value (e.g., a pixel with R=181, G=170, and B=191) may indicate a low hair growth area (e.g., such as a normal skin tone color).

Together, when a series of pixels in an analyzed region transition from dark or low RGB values to lighter RGB values (or vice versa), that may indicate a shift in the relative hair growth of the portions of the respective user's body or body area represented by the series of pixels. For example, and as described further herein, an image may feature a respective user's cheek area, wherein the user's facial hair is relatively dense near their jaw and is less dense near their cheekbones. The analyzed region may include pixels representative of the respective user's cheekbone and their jaw, such that pixels indicative of the respective user's cheek may have a lighter RGB value than the pixels indicative of the respective user's jaw. Moreover, the image may include many individual hair follicles many of which feature a tip that is distinguishable from the base. In this way, pixel data (e.g., detailing one or more features of a user, such as a respective user's body or body area including degrees of hair growth direction) of 10,000s training images may be used to train or use a machine learning imaging model to determine a hair growth direction value of the specific user's hair.

In various embodiments, wherein training, by the one or more processors (e.g., of imaging server(s) 102) with the pixel data of the plurality of training images, the hair growth direction model (e.g., hair growth direction model 108) comprises training the hair growth direction model (e.g., hair growth direction model 108) to detect a displacement of a tip of a hair follicle with respect to a base of the hair follicle on the user's skin to determine the user-specific hair growth direction value of the user's hair. In such embodiments, the hair growth direction model may be trained to recognize that closely clustered pixels with darker values (e.g., darker or lower RGB values) surrounded by lighter pixels (e.g., brighter or higher RGB values) may indicate an individual hair follicle on the specific user's skin. The hair growth direction model may then link the darker pixels and determine a hair growth direction value corresponding to the hair follicle based on the determined tip and base of the hair follicle. For example, for image 202 a, pixel 202 ap 1 is a dark pixel positioned in image 202 a resulting from user 202 au having a relatively high degree of hair growth direction at the position represented by pixel 202 ap 1 due to, for example, the hair on the user's 202 au neck approaching a dense region of user's 202 au facial hair (e.g., on the user's 202 au jaw). The hair growth direction model may recognize that pixel 202 ap 1 is closely clustered near other pixels with darker values (e.g., darker or lower RGB values) and is surrounded by lighter pixels (e.g., brighter or higher RGB values). The hair growth direction model may then recognize that the pixel 202 ap 1 is part of a hair follicle on the user's 202 au neck. The hair growth direction model may then link the darker pixels and determine a hair growth direction value corresponding to the hair follicle based on the determined tip and base of the hair follicle. In this manner, the hair growth direction model can identify patterns within the pixel data to determine a hair growth direction value of the specific user's hair.

In various embodiments, the hair growth direction model (e.g., hair growth direction model 108) may be further trained, by one or more processors (e.g., of imaging server(s) 102) with the pixel data of the plurality of training images, to output one or more location identifiers indicating one or more corresponding body area locations of respective users. In such embodiments, the hair growth direction model (e.g., hair growth direction model 108), executing on the one or more processors (e.g., imaging server(s) 102) and analyzing the at least one image of the user, can determine a location identifier indicating a body area location of the user's body or body area. For example, body area locations may comprise a user's neck, a user's jaw, a user's cheek, a user's head, a user's groin, a user's underarm, a user's chest, a user's back, a user's leg, a user's arm, and/or a user's bikini area. For example, each of images 202 a, 202 b, and 202 c illustrate example body area locations including a user's neck, a user's jaw, and a user's cheek, respectively.

With reference to FIG. 3 , at block 306 method 300 comprises receiving, at the one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111 c 1), at least one image of a user. The at least one image may have been captured by a digital camera. Additionally, the at least one image may comprise pixel data of the user's body or body area.

In some embodiments, the at least one image comprises a plurality of images. In these embodiments, the plurality of images may be collected using a digital camera. For example, a user (e.g., any of users 202 au, 202 bu, and 202 cu) may shave/trim multiple areas on their body and/or on a single body part. Accordingly, the user may collect multiple images, each featuring a respective body part or skin area intended to be shaved/trimmed for analysis by the hair growth direction model (e.g., hair growth direction model 108).

At block 308 method 300 comprises analyzing, by the hair growth direction model (e.g., hair growth direction model 108) executing on the one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111 c 1), the at least one image captured by the digital camera to determine a user-specific hair growth direction value of the user's hair.

At block 310 method 300 comprises generating, by the one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111 c 1) based on the user-specific hair growth direction value, at least one product recommendation designed to address at least one feature identifiable within the pixel data of the user's body or body area. For example, the at least one product recommendation may be a user-specific product recommendation for a manufactured product. Accordingly, the manufactured product may be designed to address at least one feature identifiable within the pixel data of the user's body or body area.

At optional block 312 method 300 comprises rendering, on a display screen of a user computing device, the at least one product recommendation. A user computing device may comprise at least one of a mobile device, a tablet, a handheld device, or a desktop device, for example, as described herein for FIG. 1 . In some embodiments, the user computing device (e.g., user computing device 111 c 1) may receive the at least one image comprising the pixel data of the user's body or body area. In such embodiments, and the user computing device may execute the hair growth direction model (e.g., hair growth direction model 108) locally and generate, based on output of the hair growth direction model (e.g., hair growth direction model 108), the at least one product recommendation. The user computing device (e.g., user computing device 111 c 1) may then render the at least one product recommendation on its display screen.

Additionally, or alternatively, in other embodiments, the imaging server(s) 102 may analyze the user image remote from the user computing device to determine the user-specific hair growth direction and/or user-specific product recommendation designed to address at least one feature identifiable within the pixel data of the user's body or body area. For example, in such embodiments imaging server or a cloud-based computing platform (e.g., imaging server(s) 102) receives, across computer network 120, the at least one image comprising the pixel data of the user's body or body area. The server or a cloud-based computing platform may then execute hair growth direction model (e.g., hair growth direction model 108) and generate, based on output of the hair growth direction model (e.g., hair growth direction model 108), the user-specific product recommendation. The server or a cloud-based computing platform may then transmit, via the computer network (e.g., computer network 120), the user-specific recommendation to the user computing device for rendering on the display screen of the user computing device.

In some embodiments, the user may submit a new image to the hair growth direction model for analysis as described herein. In such embodiments, one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111 c 1) may receive a new image of the user. The new image may been captured by a digital camera of user computing device 111 c 1. The new image may comprise pixel data of the user's body or body area. For example, a user may initially submit an image of their cheek area (e.g., as illustrated in FIG. 2C) before, during, or after shaving/trimming their cheek. The user may then subsequently submit a new image featuring the user's cheek, the user's jaw (e.g., as illustrated in FIG. 2B), the user's neck (e.g., as illustrated in FIG. 2A), and/or any other suitable body area.

The hair growth direction model (e.g., hair growth direction model 108) may then analyze, on the one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111 c 1), the new image captured by the digital camera to determine a new user-specific hair growth direction value of the user's hair. A new product recommendation may be generated, based on the new user-specific hair growth direction value, regarding at least one feature identifiable within the pixel data of the new image. The new product recommendation may be a user-specific recommendation for a new manufactured product. For example, the user may initially submit an image of their neck area, and receive a product recommendation for shave gel or shaving cream. The user may then receive, after submission of a new image featuring their cheek, a new product recommendation for an aftershave product. The new product recommendation or comment (e.g., message) may then be rendered on a display screen of a user computing device of the user. Further in these embodiments, the new image of the user comprises pixel data indicative of a hair removal associated with at least a portion of the user's body or body area represented in the at least one image of the user, and the new manufactured product is designed to address the hair removal associated with at least a portion of the user's body or body area. For example, a user may submit an image featuring their cheek in an unshaven/untrimmed state. The user may shave/trim their cheek area, capture a new image featuring their shaved/trimmed cheek area (e.g., image 202 c, specifically pixel 202 cp 2), and receive a new product recommendation for a product designed to address the user's hair removal.

In some embodiments, the hair growth direction model may compare the new user-specific hair growth direction value and the user-specific hair growth direction value to generate a composite hair growth direction value. Moreover, the new product recommendation may be further based on the composite hair growth direction value, and the composite hair growth direction value may be rendered on the display screen of the user computing device. In further embodiments, the new image comprises pixel data of a different portion of the user's body or body area relative to the at least one image. For example, the at least one image may be of a user's jaw, and the new image may be of the user's neck. The hair growth direction model may then generate the composite hair growth direction value by comparing the new user-specific hair growth direction value of the user's neck with the user-specific hair growth direction value of the user's jaw. As a result, the user computing device (e.g., user computing device 111 c 1) and/or imaging server(s) may generate the new product recommendation and may include a manufactured product as well as behavior and or hair style recommendations based on the composite hair growth direction value. To illustrate, the user's neck may have a downward user-specific hair growth direction value user's jaw may have a generally leftward and/or rightward user-specific hair growth direction value. Accordingly, the user computing device may generate a new product recommendation indicating that the user may want to consider shaving their neck with a shaving gel/cream, and not shave their jaw to grow a beard that they can maintain and groom with a recommended beard oil. Moreover, if the user specifies that they desire a beard, the user computing device may analyze the respective user-specific hair growth direction values included in the composite hair growth direction value to recommend that the user shave their neck to create less of a contrast in hair growth direction between their neck and their jaw.

Additionally or alternatively, the hair growth direction model may compare the new user-specific hair growth direction value and the user-specific hair growth direction value to generate a composite hair growth direction value. For example, the hair growth direction model may generate the user-specific hair growth direction value before a user shaves their face, and the hair growth direction model may generate the user-specific hair growth direction value after the user shaves their face. Moreover, the hair growth direction model may compare a new user-specific hair growth direction value generated several shaves after the user-specific hair growth direction value was generated. The composite hair growth direction value may then represent the user's change in hair growth direction value across multiple shaves, and/or it may represent the hair growth direction model acknowledging that the user has completed their shave. In either case, the hair growth direction model may more acutely recommend products or techniques to the user based upon the generated composite hair growth direction value. For example, if the composite hair growth direction value represents a user having completed their shave, the composite hair growth direction value may reflect that by indicating a different hair growth direction value from the beginning of the shave (e.g., the user-specific hair growth direction value) to the end of the shave (e.g., the new user-specific hair growth direction value). In addition, if the hair growth direction model compares a new user-specific hair growth direction value generated several shaves after the user-specific hair growth direction value was generated, the composite hair growth direction value may reflect a systemic change in hair growth direction of the user's hair on the particular body area represented in the images by indicating a different hair growth direction value from the earlier shave image (e.g., the user-specific hair growth direction value) to the later shave image (e.g., the new user-specific hair growth direction value). Further in these embodiments, the new product recommendation may be based on the composite hair growth direction value, and the composite hair growth direction value may be rendered on the display screen of a user computing device (e.g., user computing device 111 c 1).

In some embodiments, at least one product recommendation may be displayed on the display screen of a user computing device (e.g., user computing device 111 c 1) with a graphical representation of the user's body or body area as annotated with one or more graphics or textual renderings corresponding to the user-specific hair growth direction value. In still further embodiments, the at least one product recommendation may be rendered in real-time or near-real time during or after the user shaves/trims their body or body area.

In additional embodiments, at least one product recommendation may be displayed on the display screen of a user computing device (e.g., user computing device 111 c 1) with instructions (e.g., a message) for treating, with the manufactured product, the at least one feature identifiable within the pixel data of the user's body or body area. In still further embodiments, either the user computing device 111 c 1 and/or imaging server(s) may initiate, based on the at least one product recommendation, the manufactured product for shipment to the user.

In some embodiments, the user computing device (e.g., user computing device 111 c 1) and/or imaging server(s) may select, based upon the user-specific hair growth direction value, a recommended behavior from at least two available behaviors. Further in these embodiments, the at least one product recommendation may include the recommended behavior. For example, the user computing device may recommend that a user shave all or a portion of their body or body area featured in the at least one image if the user-specific hair growth direction value changes one or more times within a single area, and thus might negatively impact the visual appearance of hair growth in that single area. By contrast, the user computing device may recommend that a user not shave all or a portion of their body or body area featured in the at least one image if the user-specific hair growth direction value is relatively constant (e.g., to achieve a particular hair style). The user computing device may then include a suitable product in the at least one product recommendation to assist the user in accomplishing the recommended behavior (e.g., new razors to achieve a closer shave, shaving gel to reduce skin irritation in areas where the user may shave against the grain, beard oil to maintain a beard, etc.).

In further embodiments, the at least one product recommendation may be displayed on a display screen of the user computing device with an augmented graphical representation of the user's body or body area. The augmented graphical representation may include at least one recommended hair style corresponding to the user-specific hair growth direction value, and the at least one recommended hair style may be a feature that is graphically augmented onto the representation of the user's face as part of the augmented graphical representation as a prediction of the user's appearance with the feature. Generally, certain hair styles may only be achievable with specific hair growth direction values, and it is often difficult for a user to know what is achievable given their user-specific hair growth direction. To solve this problem, the user computing device (e.g., user computing device 111 c 1) and/or imaging server(s) may utilize the user-specific hair growth direction to identify hair styles that may be preferable for a user based upon their user-specific hair growth direction. Accordingly, the at least one recommended hair style may be a list of the best potential hair styles a user may want to try based upon their user-specific hair growth direction. Moreover, the at least one product recommendation may be specifically intended to help the user achieve the at least on recommended hair style (e.g., shaving products, styling products, etc.).

As an example of the above embodiment, if a user has a dense grouping of hairs on their upper lip with a relatively constant user-specific hair growth direction value, and a more sparse grouping of hairs on their jaw with a number of inconsistent user-specific hair growth direction values, the at least one product recommendation may include a recommendation for the user to grow a mustache. Further in this example, the user computing device (e.g., user computing device 111 c 1) and/or imaging server(s) may render a graphical representation of a mustache onto the user's upper lip to generate the augmented graphical representation of the user's body or body area. The user computing device may then display the augmented graphical representation featuring the user's face on the display screen. The user computing device may also display the at least one product recommendation suggesting that the user may want grooming products (e.g., shaving gel/cream, razors, aftershave) to shave the hair on their jaw and/or styling products (e.g., mustache wax, etc.) to maintain the look and/or feel of the at least one recommended hair style (a mustache).

In some embodiments, the user computing device is a retail computing device. Further in these embodiments, and in response to rendering the at least one product recommendation, the retail computing device may dispense the manufactured product for retrieval by the user. As an example, the retail computing device may render an at least one product recommendation on a display recommending that a user utilize shaving gel when shaving areas in which the user may desire a particularly close shave, and may therefore shave against the grain. The retail computing device may then dispense shaving gel in accordance with the at least one product recommendation that the user may then retrieve from the retail computing device and purchase within the retail location. Additionally or alternatively, the retail computing device may provide an additional recommendation included in the at least one product recommendation providing the user with directions and/or a general location where the user may find the recommended product (e.g., the manufactured product) within the retail location in which the retail computing device is located. For example, the retail computing device may recommend shaving gel and additionally inform the user that shaving gel is located in the fifth isle of the retail location.

FIG. 4 illustrates an example user interface 402 as rendered on a display screen 400 of a user computing device 111 c 1 in accordance with various embodiments disclosed herein. For example, as shown in the example of FIG. 4 , user interface 402 may be implemented or rendered via an application (app) executing on user computing device 111 c 1.

For example, as shown in the example of FIG. 4 , user interface 402 may be implemented or rendered via a native app executing on user computing device 111 c 1. In the example of FIG. 4 , user computing device 111 c 1 is a user computer device as described for FIG. 1 , e.g., where 111 c 1 is illustrated as an APPLE iPhone that implements the APPLE iOS operating system and has display screen 400. User computing device 111 c 1 may execute one or more native applications (apps) on its operating system. Such native apps may be implemented or coded (e.g., as computing instructions) in a computing language (e.g., SWIFT) executable by the user computing device operating system (e.g., APPLE iOS) by the processor of user computing device 111 c 1.

Additionally, or alternatively, user interface 402 may be implemented or rendered via a web interface, such as via a web browser application, e.g., Safari and/or Google Chrome app(s), or other such web browser or the like.

As shown in the example of FIG. 4 , user interface 402 comprises a graphical representation (e.g., image 202 a) of the user's skin. Image 202 a may be the at least one image (or graphical representation thereof) of the user's body or body area as analyzed by the hair growth direction model (e.g., hair growth direction model 108) as described herein. In the example of FIG. 4 , graphical representation (e.g., image 202 a) of the user's body or body area is annotated with one or more graphics (e.g., area of pixel data 202 ap) or textual rendering (e.g., text 202 at) corresponding to the user-specific hair growth direction. For example, the area of pixel data 202 ap may be annotated or overlaid on top of the image of the user (e.g., image 202 a) to highlight the area or feature(s) identified within the pixel data (e.g., feature data and/or raw pixel data) by the hair growth direction model (e.g., hair growth direction model 108). In the example of FIG. 4 , the feature(s) identified within area of pixel data 202 ap may include the user-specific hair growth direction of the user's neck area, the hair growth direction of the portion of the user's neck represented by pixel 202 ap 2, irritation of the skin, skin type, skin tone, and other features shown in area of pixel data 202 ap. In various embodiments, the pixels identified as the specific features indicating hair growth direction values (e.g., pixel 202 ap 1 and pixel 202 ap 2) may be highlighted or otherwise annotated when rendered.

Textual rendering (e.g., text 202 at 1, 202 at 2) shows a user-specific hair growth direction value (e.g., Left, Right, etc.) which illustrates that the user's hair growth direction value is left, right, upward, downward, etc. in the indicated region of the user's neck. Graphical rendering (e.g., arrow 202 at 3, 202 at 4) shows a user-specific hair growth direction value corresponding to the textual renderings (e.g., text 202 at 1, 202 at 2) by illustrating the user's hair growth direction value, for example, at an associated pixel and/or group of pixels (e.g., pixel 202 ap 1, 202 ap 2, and surrounding pixels). The left hair growth direction value, for example, indicates that the user's hair in the indicated area may grow to the left from the user's perspective, and as such, the user may want to take precautions when moving a razor or other shaving device to the right across the indicated section of their neck when shaving/trimming the indicated region of their neck (e.g., using a shaving gel/cream, washing user's neck with warm water pre-shave/trim). It is to be understood that other textual rendering types or values are contemplated herein, where textual rendering types or values may be rendered, for example, as percentage of area with a particular hair growth direction value, number of different hair growth direction values included in region of interest, or the like. Additionally, or alternatively, color values may be used and/or overlaid on a graphical representation shown on user interface 402 (e.g., image 202 a) to indicate hair growth direction values (e.g., heat-mapping, as described herein).

User interface 402 may also include or render a user-specific electronic recommendation 412. In the embodiment of FIG. 4 , user-specific electronic recommendation 412 comprises a message 412 m to the user designed to address at least one feature identifiable within the pixel data of the user's body or body area. As shown in the example of FIG. 4 , message 412 m recommends to the user to apply a shaving gel or cream to their neck to soften the neck hair and reduce skin irritation while shaving.

Message 412 m further recommends that the user should shave to the left on the right side of their neck and to the right on the left side of their neck. The directional shaving recommendation can be made based on the hair growth direction value associated with the user's neck. For example, the hair growth direction model may be designed to generate recommendations that user's shave with the grain (e.g., message 412 m) in order to minimize potential skin irritation or cuts. Alternatively, the hair growth direction model may be designed to generate recommendations that user's shave against the grain (e.g., message 412 m) in order to maximize shave closeness. In any event, the user may have an option to specify their intended and/or preferred shaving direction such that the hair growth direction model may more accurately tailor the recommendations (e.g., message 412 m) to the user's preferences. Accordingly, the shaving gel or cream product is designed to address the issue of skin irritation and/or cuts detected in the pixel data of image 202 a or otherwise assumed based on the hair growth direction value(s). The product recommendation can be correlated to the identified feature within the pixel data, and the user computing device 111 c 1 and/or server(s) 102 can be instructed to output the product recommendation when the feature (e.g., excessive pressure, skin irritation, skin dehydration, cuts, etc.) is identified.

User interface 402 may also include or render a section for a product recommendation 422 for a manufactured product 424 r (e.g., shaving cream, as described above). The product recommendation 422 generally corresponds to the user-specific electronic recommendation 412, as described above. For example, in the example of FIG. 4 , the user-specific electronic recommendation 412 is displayed on display screen 400 of user computing device 111 c 1 with instructions (e.g., message 412 m) for treating, with the manufactured product (manufactured product 424 r (e.g., shaving cream)) at least one feature (e.g., hair growth direction value(s) at pixel 202 ap 1, 202 ap 2) identifiable in the pixel data (e.g., pixel data 202 ap) of the user's body or body area (e.g., the user's neck).

As shown in FIG. 4 , user interface 402 recommends a product (e.g., manufactured product 424 r (e.g., shaving cream)) based on the user-specific electronic recommendation 412. In the example of FIG. 4 , the output or analysis of image(s) (e.g. image 202 a) of hair growth direction model (e.g., hair growth direction model 108), e.g., user-specific electronic recommendation 412 and/or its related values (e.g., Left, Right, etc.) or related pixel data (e.g., 202 ap 1 and/or 202 ap 2), may be used to generate or identify recommendations for corresponding product(s). Such recommendations may include products such as shaving gel, new shaving razor(s), shaving blade(s), aftershave, or the like to address the user-specific issue as detected within the pixel data by the hair growth direction model (e.g., hair growth direction model 108).

In the example of FIG. 4 , user interface 402 renders or provides a recommended product (e.g., manufactured product 424 r) as determined by hair growth direction model (e.g., hair growth direction model 108) and its related image analysis of image 202 a and its pixel data and various features. In the example of FIG. 4 , this is indicated and annotated (424 p) on user interface 402.

User interface 402 may further include a selectable UI button 424 s to allow the user (e.g., the user of image 202 a) to select for purchase or shipment the corresponding product (e.g., manufactured product 424 r). In some embodiments, selection of selectable UI button 424 s may cause the recommended product(s) to be shipped to the user (e.g., user 202 au) and/or may notify a third party that the user is interested in the product(s). For example, either user computing device 111 c 1 and/or imaging server(s) 102 may initiate, based on user-specific electronic recommendation 412, the manufactured product 424 r (e.g., shaving cream) for shipment to the user. In such embodiments, the product may be packaged and shipped to the user.

In various embodiments, graphical representation (e.g., image 202 a), with graphical annotations (e.g., area of pixel data 202 ap), textual annotations (e.g., text 202 at), user-specific electronic recommendation 412 may be transmitted, via the computer network (e.g., from an imaging server 102 and/or one or more processors) to user computing device 111 c 1, for rendering on display screen 400. In other embodiments, no transmission to the imaging server of the user's specific image occurs, where the user-specific recommendation (and/or product specific recommendation) may instead be generated locally, by the hair growth direction model (e.g., hair growth direction model 108) executing and/or implemented on the user's mobile device (e.g., user computing device 111 c 1) and rendered, by a processor of the mobile device, on display screen 400 of the mobile device (e.g., user computing device 111 c 1).

In some embodiments, any one or more of graphical representations (e.g., image 202 a), with graphical annotations (e.g., area of pixel data 202 ap, arrow 202 at 3, 202 at 4), textual annotations (e.g., text 202 at 1, 202 at 2), user-specific electronic recommendation 412, and/or product recommendation 422 may be rendered (e.g., rendered locally on display screen 400) in real-time or near-real time before, during, and/or after the user shaves their respective body or body area. In embodiments where the image is analyzed by imaging server(s) 102, the image may be transmitted and analyzed in real-time or near real-time by imaging server(s) 102.

In some embodiments, the user may provide a new image that may be transmitted to imaging server(s) 102 for updating, retraining, or reanalyzing by hair growth direction model 108. In other embodiments, a new image that may be locally received on computing device 111 c 1 and analyzed, by hair growth direction model 108, on the computing device 111 c 1.

In addition, as shown in the example of FIG. 4 , the user may select selectable button 412 i to for reanalyzing (e.g., either locally at computing device 111 c 1 or remotely at imaging server(s) 102) a new image. Selectable button 412 i may cause user interface 402 to prompt the user to attach for analyzing a new image. Imaging server(s) 102 and/or a user computing device such as user computing device 111 c 1 may receive a new image of the user before, during, and/or after shaving/trimming all or a portion of the user's body or body area. The new image may be captured by the digital camera. The new image (e.g., just like image 202 a) may comprise pixel data of the user's body or body area. The hair growth direction model (e.g., hair growth direction model 108), executing on the memory of the computing device (e.g., imaging server(s) 102), may analyze the new image captured by the digital camera to determine a new user-specific hair growth direction value of the user's body or body area. The computing device (e.g., imaging server(s) 102) may generate, based on the new user-specific hair growth direction value, a new user-specific electronic recommendation or comment regarding at least one feature identifiable within the pixel data of the new image. For example, the new user-specific electronic recommendation may include a new graphical representation including graphics and/or text (e.g., showing a new user-specific hair growth direction value, e.g., Upward, Downward, etc.). The new user-specific electronic recommendation may include additional recommendations, e.g., that the user has an upward hair growth direction, as detected with the pixel data of the new image, and should move a razor or other hair removal device in an upward direction while shaving to lessen skin irritation. A comment may include that the user has corrected the at least one feature identifiable within the pixel data (e.g., the user has little or no skin irritation after shaving/trimming).

In some embodiments, the new user-specific recommendation or comment may be transmitted via the computer network to the user computing device of the user for rendering on the display screen of the user computing device. In other embodiments, no transmission to the imaging server of the user's new image occurs, where the new user-specific recommendation (and/or product specific recommendation) may instead be generated locally, by the hair growth direction model (e.g., hair growth direction model 108) executing and/or implemented on the user's mobile device (e.g., user computing device 111 c 1) and rendered, by a processor of the mobile device, on a display screen of the mobile device (e.g., user computing device 111 c 1).
